1. A system for use with a drug delivery device having a drug in a reservoir, the system comprising:
- a sensor unit configured to detect a characteristic in a local environment and generate an output corresponding to a value of the detected characteristic; and
a deactivation unit operatively coupled to the sensor unit and to the reservoir, the deactivation unit having control circuitry and an energy source, the control circuitry configured to initiate application of energy from the energy source to the reservoir;
wherein the control circuitry is configured to apply the energy to the reservoir to neutralize the drug in the reservoir when the sensor unit detects a condition in the local environment using the characteristic of the local environment.

Abstract
A system for use with a drug delivery device includes a sensor unit and a deactivation unit operatively coupled to an output of the sensor unit and to a drug-retaining region of the drug delivery device, wherein the drug-retaining region contains a drug. The sensor unit is configured to detect a characteristic of a local environment and generate an output corresponding to a value of the detected characteristic. The deactivation unit is configured to render the drug ineffective when the output of the sensor unit satisfies a predetermined condition.
